Global environmental changes using satellite data and remote sensing technologies

My main research areas include monitoring ground subsidence in urban areas and analyzing hydrological changes in the Amazon and African Congo wetlands. Currently, I am focusing on studying water resource cycles in the African Sahel and Nile River basins to address water scarcity issues, and domestically, I am developing satellite imagery-based marine monitoring systems to support scientific policy decision-making. Recently, I have been conducting in-depth research on land-atmosphere-ocean interactions in the East Asian region, striving to establish a scientific foundation for climate change response. I obtained my Bachelor's (1998) and Master's (2003) degrees in Earth System Sciences from Yonsei University, and received my Ph.D. in Earth Sciences (2011) from The Ohio State University in the United States. My doctoral dissertation was on "Wetland Hydrodynamics Research Using Interferometric Synthetic Aperture Radar, Remote Sensing, and Modeling." I worked at NASA Goddard Space Flight Center (GSFC) for approximately 9 years (2011-2020), starting as a postdoctoral researcher and advancing to senior researcher, conducting various projects including ecosystem and disaster research using radar, water resource research through satellite observations, and development of extreme hydrological phenomenon prediction systems for West Africa. From 2020 to 2023, I worked as a senior researcher at the Korea Institute of Ocean Science and Technology (KIOST) Marine Satellite Center, conducting research on spatiotemporal variability of coastal wetlands using synthetic aperture radar and developing satellite-based ship distribution monitoring and prediction systems. During the same period, I also served as an associate professor in the field of marine science and technology at the University of Science and Technology (UST). Since March 2023, I have been serving as an associate professor in the Department of Earth System Sciences at Yonsei University, dedicating myself to research and education in satellite Earth science and satellite hydrology. - From Yonsei News -
